Why this decision is easy to misread
Refinancing advertisements emphasise the new rate and cashback because those figures are easy to market. The less visible side is the collection of fees and structural costs that sit around settlement.
Some costs are one-off. Others recur every year or appear through a higher rate attached to a feature package. Both belong in the comparison.
Home loans are amortising debts: every repayment includes interest and, for principal-and-interest loans, a principal component. A lower advertised rate changes that split, but fees and a longer term can reverse the apparent saving. The clean comparison uses the same balance, realistic fees and a clearly chosen payoff date.
Loan products also differ in offset access, redraw rules, fixed-rate conditions and package fees. Those features can be valuable, but they should be priced rather than treated as free extras.
The calculation, step by step
Discharge fee
The existing lender may charge to close the loan and release security.
In the calculator, this item should be entered separately so a change in discharge fee can be tested without hiding it inside another assumption. Keeping the input visible also makes later reviews and comparisons more reliable.
Break cost
A fixed-rate contract can create a large economic break cost that changes as wholesale rates and time remaining change.
In the calculator, this item should be entered separately so a change in break cost can be tested without hiding it inside another assumption. Keeping the input visible also makes later reviews and comparisons more reliable.
Application and settlement
The new lender may charge application, legal, valuation or settlement fees.
In the calculator, this item should be entered separately so a change in application and settlement can be tested without hiding it inside another assumption. Keeping the input visible also makes later reviews and comparisons more reliable.
LMI
Borrowers with insufficient equity may face new lender’s mortgage insurance even if they paid it on the original loan.
In the calculator, this item should be entered separately so a change in lmi can be tested without hiding it inside another assumption. Keeping the input visible also makes later reviews and comparisons more reliable.
Annual package fees
A lower rate can be paired with annual fees, card conditions or account fees.
In the calculator, this item should be entered separately so a change in annual package fees can be tested without hiding it inside another assumption. Keeping the input visible also makes later reviews and comparisons more reliable.
Term cost
Extending the payoff date is not a line-item fee, but it can be the largest cost in the transaction.
In the calculator, this item should be entered separately so a change in term cost can be tested without hiding it inside another assumption. Keeping the input visible also makes later reviews and comparisons more reliable.
Worked Australian example
Imagine a refinance with a $2,000 cashback, a $350 discharge fee and no application fee. It looks like a $1,650 gain. Add a $2,800 fixed break cost, $395 annual package fee and a five-year term extension, and the economics change completely.
Enter each amount separately rather than netting them mentally. That makes it easier to update the model when one lender waives a fee or the break quote changes.
Decision checklist
| Step | What to confirm |
|---|---|
| 1 | Request current break and discharge quotes. |
| 2 | Check equity against the new lender’s valuation, not your estimate. |
| 3 | List annual fees for the entire expected holding period. |
| 4 | Confirm whether cashback has clawback conditions. |
| 5 | Price any lost offset or redraw feature. |

Common mistakes
- Assuming an online property value avoids LMI.
- Ignoring break costs until application.
- Counting waived fees twice.
- Leaving annual package fees out of lifetime cost.
- Treating term extension as free.

Frequently asked questions
Can lenders waive refinance costs?
Some can, but obtain the waiver in writing and still model all remaining costs.
Is LMI transferable?
Usually not in a simple sense; ask the current and proposed lenders about any refund or new premium.
Do government charges apply?
They can. Confirm title, registration and jurisdiction-specific charges.
Can cashback be clawed back?
Some offers have conditions, including minimum holding periods.
Why include annual fees in break-even?
They reduce the monthly or annual saving and can delay or prevent break-even.
Sensitivity check before acting
Stress-test the proposed interest rate, all switching costs and the new loan term. A refinance that only works with a short-lived introductory rate or an extended term has a much weaker margin of safety than the monthly repayment suggests.
For Home Loan Refinancing Costs Australians Commonly Overlook, keep the base, conservative and stress cases together. The decision is stronger when it survives a realistic adverse change rather than depending on one precise forecast.
Bottom line
The overlooked costs are rarely one dramatic fee; they are the combined effect of several small charges and a longer debt timeline.
